fakeroot @1.19-2_0: error: conflicting types for 'openat'

[liam.sharp@…]

I'm using OS X 10.10.5 with XCode 7.1.1 (7B1005) and I'm unable to install fakeroot.

Portfile

[florian@…]

I uploaded a new Portfile and two patches. I don't have 10.10 so I need you to test this for me. Thanks.

[liam.sharp@…]

Hi florian - Happy to test, what do I need to do to test?

[florian@…]

Hi, you have to update the ports tree, replace the fakeroot Portfile, and add the two patchefiles. Then you can test building fakeroot. Assuming you have downloaded the files to your ${HOME}/Downloads folder, in the terminal you would have to do:

sudo port selfupdate
fakeroot_portdir=$(port dir fakeroot)
sudo cp ~/Downloads/Portfile $fakeroot_portdir
sudo mkdir ${fakeroot_portdir}/files
sudo cp ~/Downloads/{patch-libfakeroot.c.diff,patch-wrapfunc.inp.diff} ${fakeroot_portdir}/files

Then build fakeroot and if that succeeds test and install:

port -v build fakeroot
port -v test fakeroot
sudo port -v install fakeroot

[liam.sharp@…]

Thanks for the info, much appreciated.

Failed at the build step, tried with sudo but failed again - will attach log.

Permission problem. Either build as root or:

chmod a+rx /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/sysutils/fakeroot/files
chmod a+r /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/sysutils/fakeroot/files/*

[liam.sharp@…]

I built using sudo before, so modified permissions as suggested. I'll attach a log of the build failure.

[liam.sharp@…]

log of build failure after modifying permissions

[florian@…]

I uploaded a new patch-wrapfunc.inp.diff. Please download that file and replace the one on your disk in /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/sysutils/fakeroot/files/ and try again.

[liam.sharp@…]

Build failure with new patch (I cleaned after the initial build failed to see the new patch get applied)

[florian@…]

Yes the patch was not applied. Your current build failure is the same as the first one. With the current patch applied, wraptmpf.h should look like this

576 #ifdef HAVE_OPENAT
577 extern int openat (int dir_fd, const char *pathname, int flags, ...);
578
579 #endif /* HAVE_OPENAT */

after the configure phase.

You need to port clean --all fakeroot or wipe the entire build directory before rebuilding.

[liam.sharp@…]

Excellent, thanks. Build succeeded, but seems to have a symbol issue when run. I'll attach the success build logs for reference.

Sorry, I forgot to edit patch-libfakeroot.c.diff. Please replace that file too. Then clean and uninstall fakeroot and test rebuilding again.

I get the same issue when trying to run it, I've attached the log so you can double check my steps.

I updated the patches for upgrading fakeroot to the most recent version. It builds and runs successfully on OSX <10.10. Fakeroot also builds on more recent OSX versions but it does not function anymore. The tests fail and the installed binary runs but is dysfunctional. I have no clue why and I don't have time to further investigate.

Someone with commit rights please commit the relevant files: Portfile.diff, patch-libfakeroot.c.diff, patch-message.h.diff, patch-wrapfunc.inp.diff.

A note for those who may want to try and make it work: I tested pseudo (​http://git.yoctoproject.org/cgit/cgit.cgi/pseudo/) as well. Same result: compiles but only works on OSX <10.10. We can conclude that some underlying functionality of the base system changed and that the hack does not work anymore.

The Homebrew guys did not succeed either (comment 2, ​https://github.com/Homebrew/homebrew/issues/46927#issuecomment-164103551). They fixed the build issue but fakeroot is dysfunctional as of OSX 10.10. I suggest we do the same and close this issue.
